The php-PHP _ GET array is empty.

In this case, we transplanted php to the embedded system, but when writing a script to display it by page, we must obtain the current page ($ cpageisset ($ _ GET [& quot; page & quot;])? $ _ GET [& quot; page & quot;]: 1;), but this sentence cannot work normally. echo $ _ GET; only displays one array. What should I do? Or can I change the statement to get the current page? Php
